Abstract

A method, network node and a computer program product for controlling predictive scheduling in a wireless communication network (10) between a base station (12) applying predictive scheduling for a mobile station (20) according to an uplink transmission scheme, wherein the uplink transmission scheme schedules a plurality of uplink transmission grants to be transmitted from the base station to the mobile station without having received a scheduling request from the mobile station requesting the uplink transmission grants. The method comprises detecting channel quality for the mobile station and determining a periodicity of the uplink transmission grants based on the detected channel quality.
